Subject: System hang with EXT4
Date: Mon, 23 Nov 2009 18:16:06 -0800 [thread overview]
Message-ID: <150c16850911231816t514bb1dds4deb541b14a5bad6@mail.gmail.com> (raw)
Hi all,
I've recently run into an issue with ext4 and delayed allocation where
my system will silently hang just seconds into a dbench run. I first
saw this using 2.6.30.9, but it still happens with 2.6.32-rc8. I've
tried with an SMP x86_64 system, and a UP i386 system. The SMP x86_64
system hangs every time for me within 15 seconds, but the UP i386
system never hangs on me. If I remount with -o nodelalloc on the SMP
system, the hang goes away. There are no messages printed out by the
kernel; it just locks hard. Has anyone seen this before? I'm just
running "dbench 500" to produce this behavior.
-Justin
